About CASE: In August 2021, the Colorado Department of Public Health and Environment (CDPHE) partnered with Children’s Hospital Colorado to start the Colorado Antimicrobial Stewardship Endeavor (CASE). CASE includes physicians, pharmacists, and epidemiologists who provide mentorship and resources to Colorado hospitals that may be new to antibiotic stewardship. Antibiotic stewardship is the effort to measure and improve how antibiotics are prescribed by clinicians and used by patients. Improving antibiotic prescribing and use is critical to effectively treat infections, protect patients from harms caused by unnecessary antibiotic use, and combat antibiotic resistance. Learn more on the antimicrobial stewardship main page

Through a series of workshops and one-on-one consultations, CASE will support hospital antibiotic stewardship programs to:

  • Create evidence-based actions to improve antibiotic stewardship. 
  • Develop procedures to track and monitor antibiotic use and reporting.
  • Extend antibiotic stewardship activities to pediatric patients.
  • Develop programs that meet state and national standards and CDC’s Core Elements of Antibiotic Stewardship.
  • Interact with antimicrobial steward peers statewide.
  • Request one-on-one consultations from the CASE team.

CASE also seeks to provide resources such as treatment guidelines, support for reporting antibiotic use to the National Healthcare Safety Network (NHSN), and links to evidence-based guidelines and tools.
